MICROCHIP MIC2033-55AYM6-T5

A high-side MOSFET power distribution switch that provides increased system reliability, utilizing 5% current-limit accuracy. It has an operating input voltage range from 2.5V to 5.5V, is internally current-limited and has thermal shutdown to protect the device and system. It is offered with either active-high or active-low logic level enable input controls, has an open-drain fault status output flag with a built-in 32 ms delay that asserts low during over current or thermal shutdown conditions. It is available in several different fixed current-limit options: 0.5A, 0.8A, 1A, and 1.2A. A capacitor-adjustable soft-start circuit minimizes inrush current in applications where high capacitive loads are used. It is offered in both 6-pin SOT-23 and 6-pin 2 mm x 2 mm thin DFN packages. It has an operating junction temperature range of -40°C to +125°C.
